Soundstage and explosive dynamics?

Have not tried the 811

In my experience damping the 511 or 811 causes more problems than it solves.

Hi , this is great stuff . Question to the Horn Guys , you’re way above my skill level , so please share . Do the high quality horn systems move the air with the authority of underhung voice coils and massive power ? My experience is limited , but on this type system ,  can you feel the drum kick on your chest ? Is this an Apples and Oranges thing ? This is a sincere question based on my lack of experience . As a youngster my Grandfather had tube systems with big EV and Altec stuff . It was a sweet , room filling sound , but it didn’t create this sort of “ Air Pressure “ sensation that comes with good live sound or a huge SS rig . Please share as I’m here to learn , not pontificate ( I’m not that smart ). Also I apologize for stepping all over this thread , but with knowledgeable sound engineers and horn experts sharing , this is a wealth of information  . BTW it seems everybody agrees on Tannoy , that says a lot too . Respectfully, Mike. 

Using highly compressed rock music to make the proclamation that your speakers don't dynamically compress music......absolutely brilliant. BTW, I like and listen to a lot of rock music. The Focals at 92 db efficient are likely very good at dynamics up to a certain point. No one hear is saying otherwise. Trying to say that they are the equal dynamically to any of the Volti Audio speakers, which are from 99 to 104 db efficient, is just plain foolishness. Again, not saying that the Focals are not good, just these are on a different level. You need to hear them to understand the difference. Dynamics and ease of presentation at any volume. And if you are comparing the sound quality to any PA system, all I can say is go seek out and hear a pair. Absolutely no contest. If I could afford the Alura, I would be permanently done with buying speakers. One of the times I heard them at Axpona, I was sitting right next to a speaker designer listening to them. I asked him what he thought and his only comment was, "Those are fantastic". 100% agree with him.
